Challenge: Copy Mirror Tree

Let’s copy a binary tree such that it mirrors the original tree.

We'll cover the following

Problem#

Given a binary tree, copy its values to create another tree that is a mirror image of the original tree.

Input#

A binary tree.

Output#

A new binary tree that is a mirror of the given binary tree.

Sample input#

The root node t.root of a binary tree will be our input for which we have to generate a mirror copy tree. We’ll generate this new tree by using the copyMirrorTree() function.

Sample output#

A CopyMirrorTree() function will return a tree, which we’ll use to pass the test case.

If the copied tree is the mirror of the original tree, the sample output will be true.
